1o. claims. (c1. 20s-4s) This invention relates to containers for holding fragile irregular objects, whereby they may be shipped without danger of breakage;

The primary object of my invention, generally considered, is a' shipping container for irregular thereby prevent breakage or other damage thereto.

Another object of my invention is to provide a container for irregular objects, such as those including a generally cylindrical portion with lateral projections, `saidhcontainer.l comprising a cradle device socketed to partially enclose the generally cylindrical body portion as well as support the lateral projections and prevent undesired shifting, while allowing rot/ation of said cylindrical portion without removal.

A further object of my invention is to provide a container for* irregular objects, such as magnetrons, which container includes a socket holdingfthe body of the object so that it does not come in'contact with the outer walls, said socket also serving to lock the object in place agains undesired shifting. 1

Astill further object of my invention is to provide aA container for irregular objects, which container includes a plurality of telescoping hollow parts and a central supporting member for holdingthe object in place on said supporting member, whereby said object may be removed by bodily lifting out of the supporting cradle without unscrewing or untying any parts.` An additional object'of my invention is a container including six main parts which telescope with respect to oneanother to make a strong closure for the protectionV of an irregularvobject such as a magnetron. y 4

Another object of my invention is to provide a container forso holding a magnetron that a protective tubeplaced over the output lead may be removed without taking the object out of the cradle of the container so` that, for example, plumbing may be connected or disconnected, with the container acting-as a jig.

A further object of. my invention isv a container, for holding a magnetron comprising a generally cylindrical portion with members projecting laterally therefrom at an` angle to oneanother, said container comprising a cradle holding said cylindrical portionin such a way that theprojecting members may be tilted, 4as to facilitate connection tions of the object away from the outer walls to `with `plumbing or the like, without removal `fro the container. Y

Referring to the drawing in detail, Vand first considering the embodiment of my invention illustrated in Figs. 1 to 5, inclusive, there is shown a magnetron Il) comprising a generally cylindrical body or anode portion II from which ns I2 project for cooling purposes, side plates I3, which are generally circular below the mid-.horizontal plane, except for notches where the cathode leads extend into the body portion, and generallykreca tangular thereabove, and a connecting top plate I4 for said side plates. In the present embodif ment, the output connection I5 extends generally in line Withthe cathode leads I6 and I1, that is, all lie in the normally horizontal plane through the center of the body portion I I. The glass enclosure i8, through which the cathode lead II extends, is shown as tipped off at I9.

In order to efficiently and economically enclose the object, such as the magnetron Ill, in a container light in Weight, while at the same time safely protecting the delicate parts such, for example, as the glass and tubes i3 and the cathode leads I6 and YIl projecting therefrom, I desirably Aform the six parts of the container of corrugated cardboard, rather than of wood or other mate rial. I donot, however, wish to be limited to the use of such material, as wood could be used if considered more desirable, although it would Weigh and cost more..

Part #1 of the container, generally designated `by lthe reference character 2l), is preferably formeelY from a rectangular piece 2l of Corrugated cardboard by bending it to u shape, that is With three panels with right angles therebetween as shown in Fig. 2, so as to snugly embrace the body II'Y of the magnetron, form the primary member of a cradle therefor, and have its side panels lie flat against the side plates I3 and ends of the anode portion I I. The magnetron is supported by its top plate I4 engaging the top edges 22 and 23 of the U-shaped member 2I. The bottom panel 24 of the U-shaped member is of an interior width corresponding with the axial length of the cylindrical portion II.

Part #2 of the container is preferably formed from a relatively long flat rectangular piece of corrugated cardboard 25 by cutting a central rectangular aperture 26 therein while hat and of such a size that it snugly receives part #l and the embraced magnetron I0, forming the secondary member of a cradle therefor. The portions of said cardboard 25 beyond the ends of the slot 25 are then bent at right angles downwardly, inwardly, and upwardly making side panels 2l, bottom panels 28 and side panels 29 forming with the remainder or top panel 40, hollow open-end box portions, the side panels 29 of which snugly engage the side edges of the side plates of part #1.

.Fart #3 of my container is preferably formed from a rectangular piece of corrugated cardboard 3l! by bending the end portions at right angles upwardly to leave a center panel 3 I, and form side panels 32.. It is then bent inwardly at right angles to provide shoulder or top portions 33, leavins a .Space therebetween to snugly receive the side panels of part #1. then downwardly at right angles to provide inner side panels 34, and at a point corresponding with the height of the side panels 2l of part #2, the end portions are bent outwardly at right angles to provide inner bracing panels 35, and of such a width that they normallv engage the inner surfaces of the panels 32. W hen said panels 32 are vertical, the inner panels 34 are also vertical and spaced to snugly engage the side panels of member #1, while the bracing panels 35 rest on the top panel 40 of the part #2.

It will, therefore, be seen that the magnetron is first fitted in part #1, then the enclosed parts thereof are tted in part #2, with the tip I9 received in opening 3E in top panel 46 of said part, and the assembled parts are then embraced betweenthe inner panels 34, bottom panel 3| and reinforcing panels 35 of part #3.

After the foregoing assembly has been effected, part #4, preferably consisting of a rectangular corrugated cardboard member 37, is placed .beneath part #3 andthe end portions bent at right angles around Iit and the parts assembled there# with, providing closing panel 38, for the opening in part #3 illustrated at the left thereof, and panel 3i! closing the opening at the 'other end thereof. Top panels 4I and 42 close the remain.- der of the top of part #3, or that not closed by the top plate I4 of the magnetron I6. The adjacent edges 43 and 44 of said top panels ,4I and i2 extend into snug engagement with the edges 45 and 45, respectively, of the top plate I4 of said magnetron.

Referring now to Fig. 3, it will be seen that, after tting part #4 about the assembled rst three parts and the magnetron, part #5, formed as a rectangular preferably corrugated cardboard box device 41 open at top and bottom, is tele# scoped over part #4, and the parts associated therewith. Part #5 is formed from a rectangular piece of material by bending four panels thereof into right angular relationship and securing the opposite ends together as by means of glued cloth 5I).

Part #6 is also a rectangular preferably corrugated cardboard .box 48, formed generally likeV memberAl and held in position, after bending its panels into right angular relationship, 4by a strip of glued cloth 53, but with a pair of opposite ends, rather than top andbottom, open. The area of each open end corresponds with the area of each end panel, 49 or 5I, of part #5, so that part #6 snugly telescopes over part #5 and the associated parts, completing the enclosure of the magnetron.

A consideration of Figs. 4 and 5 will show that the magnetron illustrated, as completely enclosed in the six parts, engages the outer part #6 only at its upper or supporting plate I4, all of the other parts beine kSpa-eed from the sides and ends. That is, there is considerable air space between the cylindrical body portion and the bottom of the container, as well as between the ends of the parts I5, I6 and I'I and the ends of said container. It will also be seen from a consideration of these figures that there are from two to four thicknesses of corrugated cardboard protecting every part of the device against breakage, except the upper supporting plate I4 f the magnetron, which is thick and adapted to withstandrelae tively severe shocks. e

It will also be seen that by virtue of the panels 4I and 42 engaging the edges 45 and 46 of the top plate I4, longitudinal shifting of the magnetron in the container is prevented, even without auxiliary fastening means. In the same way, by

virtue of the" magnetronfbody, afterxhousing'in .member #ljiitt-ing in the slot 2 6 in part #2, lat-` engagementof the top of the supporting plate i4 w'ith the upper wall 52 of the outer housing mem.. lEber 48, and theprojecting side` portionof this plate I4 resting on the top panels 33 of part #3. However, byvirtue ofthe spacing of the project- 'Ying `parts`|5, I6 and |'1 above the top panellil lof part #2, a limited amount ofhtilting-of the magnetron withrespecttofsaid partis permitted, even without complete `removalof the magnetron fromthe container.

' Referringnow to the embodiment of myvinven- 4tion illustratedv in Figs.y la-to 511, inclusive, there -ismsh'ownY a magnetron 88 comprising `a generally "Cylindrical body or Aanode portion 5| from which ns y62 project for cooling purposes.V Inthe presd ent embodiment, there are no 'side plates, as

" ,In order to enilciently and veconomically enclose 'such an object in alight-weight container` I, in this instance, also desirably form the six parts fof said container ofA corrugated cardboard, although IA do not AWish to 'be limited to this imaterial.` H l ,"Pal t #l of the container;generallyldesignated by `the reference character 68, is formed from a flat vrectangular piece 69 'of preferably corrugated cardboard by bending it at right angles to a cenftralpanel `1li, providing side Ypanels 1| and 12, andthen bending the end pieces toward one another; throughimore than right angles, `to provide right `top pana 13 and left top panel 14, the latterbeing notched as indicated at 15 and 15 Lto respectively receive the threaded enlargement 11 on the wave guide 66 and the flange portions 18 lon the output tube 64. The right-top vpanel 13' is provided with a rectangular slot 18, desirably out out prior to bending, to receive the Vcoolingvflns B2 ofI the magnetron, forming the primary member of a cradle therefor, allowing theilower ends of said fins to rest on the bottom panel l'llwhile preventing shifting by the engagement of the sides of theend fins and4 lateral edges ofall'of the iins, with the edges of the panel por- `ticn dening said slot 19.

f' Part #2 of the container 68 somewhat re- 4'sembles part #3 of the container' 20 of the rst embodiment, in that it is formed; from a rectangular "piece of preferably corrugated cardboard 88 by vbending end portions at right angles upwardly to leave center panel 8| and form side `panels 82. It is `then bent inwardly at right 'anglesto provide shoulder or topportions 83 and 84,Y adapted Vto support the top plate 63, leaving a space therebetween to snugly receive output 'portions of the magnetron, forming the secondary ,membery 'of a cradle therefor, then downwardly ,at right angles to provide inner side panels 85 and 86,. T hepanel 86 is discontinued at a point where its lower edge, when assembled, just engages the tops of the panels 13 Yand 14 of the part #1, while -the panels 83 and 85 are cut away to accommoengagesu the right sidefof said wave guide when the parts are assembled.l VThelowerportio'n of the `panel 8'5 is bent at right angles outwardly, so that-the outer edge of the vend portion 81 engages the inner side ofpanel 82 from which it extends, thereby holdngpanel 'spaced from Vpanel 82 so that the formersnugly `engages the adjacent side ofthe flange portionsf'|8.y Part #3 of the present embodiment of mycontainer-corresponds to someextent withthelower portion ofpart #5 of thevcontainerof the first embodiment, in that it is a rectangular preferably corrugated cardboard box device 88, open at top andbottorn and telescoped over part #2 and parts associated therewith. Thepre'sent part- #Slis formed from a rectangular piece of material` by bending four panelsthereof intoright angular relationship and securing the opposite endstgether, as by means of glued cloth 89.

Part #4, illustrated in Fig.- 3a, of my present container, corresponds somewhat withparttfiof thev first embodiment, except that it does not Wrap around assembled parts #1, #2 and-#3 aindthe object Yenclosed-l` thereby, but instead serves as means restinggon the top of part/#2V and theplat'e :83 of the magnetron 68to hold the latter against upward shifting from the cradle provided by parts #l and #2. It is formedfrom a rectangular preferably corrugatedicardboard member-Subent at right angles from a central panelBIf-'thereof :toprcvide` end panels 82v and"93, again bent at right angles to provide complementing side panels :84 and 95,V and thenbent at rightangle's'to pro-vide,V intermediateA normally-engaging panels 88 and 91, `and again bent at rightangles to provide panels 98 and 99, normally' lying `flat on the inner surface of the center panel 9|.` Itprovides,4 in eiect, two box like portions of= unequal size, both open at top and bottom. The' lower edges of the panels 88` and 81 are desirably notched, as indicatedlat'llll and `|82,to snug-ly receive theto-p plate [i3-of the'v magnetrnLPIn plan, it is like part l# 3,`exce];it that Yithas intermediate pane1s 96 and 91 andfinner panels es and'SLf., w' W? After fitting part #4 on top `of theV assembled magnetron in partsY #1, 2 andv 3; part #5, formedl as a preferably corrugated box device |83 openat top and bottom, is telescoped over part #4 and thenover partV #3 with theparts enclosed thereby- Part #5 is formed from-a rectangular piece of materialby bending four panels thereof into right angular'relationship and sc curing the opposite end s together asby'rneans ofgiuedlcloth ma.A i l i Part #yillustrated `fragmentarily in Figf, is also 'a rectangularrpreferably corrugated cardboard box |85, formed generally like the box7|84 andheld inposition afterbending itsA panels; into right angular relationship by va strip of gluedclot'h llljbutwith a pair of opposite ends, rather than the top" and bottom, open. The area of each open end corresponds to the area of eachA end panel |01 and |08 of part"#5, so that part #6 is snuglytelescoped over part #5 and the associated parts, completing the enclosureof the magnetron.

A consideration of Figs. 4 and 5u will show that the magnetron 68 illustrated is completely enclosed in theA six parts, while having no part engaging the outer part #6. There is consider- -able air space between the cylindrical body porinto right angular relationship and securing the oppositeends together as by means of glued A consideration. of. Figs. 4U `and 5b will show that the magnetron ||ll, illustrated, is'completely enclosed in the six `main parts, while having no part thereof engaging the outer part #6. There is considerable air space between the cylindrical body portion the associated fins and side plates |2 and H3, and all sides of the container and two or more thicknesses of corrugated cardboard lie between the radiating ns and plates and the outer surface of the container. All sides ofthe container, except the top, involve two or more thicknesses of corrugated cardboard, and the `top wall is reinforced by panels |49 and |5| which extend from the magnetron ns ||2 and end plates I3 to engage the undersurf ace thereof.

It will also be seen that by virtue of the slot |24, parts auxiliary to main part #1, and the panels |49 and |5|, undesirable shifting of the magnetron in the assembled container in any direction is effectively prevented. i

From the foregoing disclosure, it will be seen that I have shown howI to economically and effectively form shipping containers for irregular objects, three examples of such objects being given, one a magnetron withoppositely extending projections in which the projections normally lie horizontal, anothera magnetron with projections extending at right angles to one another and in which'one of said projections is normally horizontal and the other vertical, and also a magnetron in which right angle projections are both normally inclined. In all forms of my invention the magnetron is exposable, for examination from the top, byremoving one or more of the outer container members (one in the case of the rst form, and three in the case of the other two forms) while still safely held in a supporting cradle. i i
